PERFUME BOTTLE.

Application filed March 2U, 1926. -Serial No. 96,177.

This invention relates particularly 'to bottles for carrying perfume and the like and special objects oi the invention are to provide a relatively inexpensive, tight-fitting, secure, but readily opened'stopper construction i'or containers ot this nature.k

The foregoing and other desirable objects are attained in parli by making bot-h the bottle and the stopper of glass, molding loosely fitting screw threads in the neck of jthe bottle and on the stem of the stopper respectively and providing a resilient packing at the base ot the screw stem arranged to completely seal the joint when the stopper is screwed in place.

Other novel features of the invention will appear as the specification proceeds.

The drawing accompanying and forming part ot this specification illustrates one simple, practical commercial. development olf the invention, but as this illustration is primarily for purposes of disclosure it will be iluderstood that the structuremay be modiiied as occasion requires, without departure from the broad spirit and scope ot the invention as hereinafter delined and claimed.

Figure l is a side elevation of the invention as embodied in the form of a small perliume container.

Figure 2 is an enlarged broken sectional View ot' the neck portion of the bottle.

The bottle shown at 3 is of more or less ornamental t'orm indicated as a' container 'for perfume and the like, but the form and use ot the bottle may vary.

One ot the new features otl this bottle is that there is molded in the neck portion Ll ot the same, an integral internal screw thread 5. To provide ample material for this screw thread, the neck portion may be thickened or made with a relatively heavy wall, as indicated in Figure 2. At the mouth of the internal screw seat thus provided there is shown formed, a conical valve seat. 6.

The stopper 7, like the bottle or vial, is formed of glass and is provided on the stem portion ot the same with an external screw thread 8, making a tree fitting or slightly loose engagement with the screw threads in the neck. This tree iitting relation enables these parts to be made oi` glass and the screw engagement, thus provided is a mechanical connection vfor forcing the stopper into the neck and not tor etiecting a seal between these parts.

The seal between vthe stopper and `bottle neck is provided by a gasket 9 kotrubber or the like engaged about the stem of the stopper at the `base of the screw threads thereon and thereby carried by the stopper into sealing engagement with the valve seat 6. This gasket may simply be a small piece ot rubber tubing or elastic band' slipped over the stem of the stopper and held at the base ot the same behind the screw threads thereon.

The stopper is provided with a suitable external handle l0 and may have attached directly thereto, an applicator rod ll suit-- able for handling the perfume or other contents ot' the vial.

The internal screw threads may be made oversize with respect to the co-acting screw threads on the stopper by forming them wider and deeper than such co-acting threads, as indicated in Figure 2. This oversize relation allows 'tor small irregularities in the two sets ot threads and makes practicable the molding ot these screw threads as integral parts ot the bottle and stopper.

In addition to the advantages ot simplicity and inexpeusiveness, this construction is t particularly neat and pleasing to the eye and provides great possibilities in the way of ornan'ientation by the use oit specially colored glass and the like. The ring ot packing material can be quite small and is so concealed when iu use as to be practically unnoticeable, giving the article the appearance of being made entirely ot glass. The applicator rod being smooth and round and ot' less diameter than the screw threaded portion of the stem serves as a guide and mandrel for first stretching and positioning the rubber ring and for holding it while it is being slipped over the larger screw threaded part to the conical seat provided for it by the tapered portion shown in Figure 2 as joining the head or handle with the base or outer end of the` screw threaded part ot the stem. The rings can thus be quickly stretched and accurately placed on the stems, without the exercise ot' any special care or skill.

lVhat is claimed is:

A bottle for carrying perfume comprising a small glass vial having an internally, integrally screw threaded neck, aI glass stopper having a head providing a lingerhold and an externally integrally screw threaded stem projecting therefrom, the

screw thread of the neck being oversize with respect to the screw thread of the stem to compensate for inequalities in the molding of the screw threads in the cooperating Olass members and to provide a loose free htting engagement of these members, a resilient packing ring engaged about the stem ot' the stopper at the outer end of the screw threads thereon so as to be carried into sealing engagement with the end of the neck upon cooperative engagement of the loose litt-ing screw threads of the stopper and neck, the head of the stopper being tapered from the head portion down to the stem portion to provide a substantially conical seat for the packing ring and the screw stem having a smooth applicator rod of lesser diameter projecting therefrom and forming a guide for initially positioning the packing ring and facilitating the forcing of the same over the screw threads to the conical seat at the back ot said threads.

In witness whereof, I have hereunto set my hand this 26 day of August, 1925.
